new bass

I'm looking for a new bass that i'll be used to. The current bass i'm using and am completely familiar with has a 1 3/4" nut width (approx.) and it is 2 1/4" (approx.) at the 12th fret. What kind of bass would be pretty close to this? If you have any more questions about it, shoot.

well, i'm mostly asking what kind of neck should the bass i get have? (p-bass, jazz, etc.) I don't want to have to work real hard to get used to the neck. Otherwise, it has one humbucker midway between the neck and bridge, and it is passive.

on every string, anything above the 12th fret buzzes, the screw holes on the bridge cover are stripped, so there's a constant rattling, and the electronics frequently short out. I think i'll go to the store.
